Help me help this crow

[Silverwind]

There is a crow who broke his wing in such a way that it can't be fixed. We have no wild animal sanctuaries in our area that can take him, and in our area it is not legal to keep a crow as a pet. So right now he is hidden in a cage in the storage room. They are feeding him wet cat food. Don't have the option to euthanize him. What can I do to improve his situation? I was thinking about bringing him meat and fruit and bread to eat, but beyond that I am stumped.
